Abstract Biodiversity and prevalence of chewing lice on local poultry (Gallus Gallus Domesticus, family Phasianidae) have been successfully determined for five selected sites around Qaser Bin Ghashir region, Libya between November 2017 and April 2018. The total investigated chicken samples are 135, and the infected samples were found to be 94. Ticks, fleas, and mites were detected in a small quantity in addition to three different species of biting lice. The obtained results show that Asuani has the lowest amount of ectoparasites, while Suq AL-kamees samples were infected completely by 100 % prevalence of chewing lice. The calculated total average prevalence percentage (TAP, %) of all sites are ≤70%. Three species of lice were detected and identified on the local poultry, Menopon gallinae, Menacanthus stramineus and Lipeurus caponis. The most abundant species in the study area is Menopon gallinae with prevalence percentage about ≈ 69.84%. A comparison between chewing lice around Qaser Bin Ghashir region in Libya and other countries has been carried out and it was found that (TAP, %) for Algeria > (TAP, %) for Libya > (TAP, %) for USA. Finally, the study proves that Libya contains a mild status of biodiversity. Keywords: biodiversity, prevalence, chewing lice, poultry, ectoparasites arabic 11 English 52

Abstract: Traditional teaching practices and classroom do not promote many opportunities for the students to participate in the classroom or speak in the classroom rather they are like one way traffic. The teacher plays an active role and teaches deductively throughout the course. It is regarded as the silent skills which can be learned automatically by the students. But the reality is reading is one of the important receptive skills of the language which enables students to learn or acquire other important skills of the language. It is like the soul of the language which fills the entire body with positive energy. So it is equally important to understand the importance of the reading skills in teaching and learning and develop the techniques and strategies of pedagogy which will make the learning process easier. Strategies are often applied by the teachers and used by the learners to obtain the intended meaning of the text which they read. The paper intends to promote a practical application of classroom pedagogy to teach reading skills using activity-based teaching. It also emphasizes how different strategies of teaching reading and techniques can be used or utilized in teaching through different activities. Key Words: Reading skills, Strategies, Techniques, Activities based teaching arabic 13 English 83
